The nurse has provided teaching to a client who had an implantable cardioverter/defibrillator inserted. Which statement by the client indicates the need for further instruction?

“I will be ready to resume participation in the football league in two weeks.!

'It is safe to use the microwave oven to heat up food."

“I can use my cellphone as long as I keep it 6 inches away from the device."

"The defibrillator will feel like a kick or blow to the chest if it fires."

Answer and Explanation

The Correct Answer is A

A.   This statement indicates a need for further education. After receiving an ICD, clients must refrain from engaging in vigorous physical activities such as contact sports (e.g., football) for a longer period of time to avoid injury or triggering the defibrillator. A longer recovery period is typically recommended.
B.   This is correct. Microwaves do not affect the function of an ICD, so it is safe to use one.
C.   This is correct. The client should keep their cellphone at least 6 inches away from the ICD to avoid interference with the device.
D.   This is correct. Clients may experience a sudden, forceful sensation similar to a kick or blow when the ICD delivers a shock to correct an arrhythmia.

Correct Answer is A

Explanation

A. Dopamine at low doses primarily increases renal perfusion, which can lead to improved urine output. An increase in urine output is a key indicator that the medication is effectively improving kidney function and blood flow. This is the most direct way to assess its effectiveness.
B. A decrease in blood pressure is not an expected effect of low-dose dopamine, which should actually help improve perfusion and raise blood pressure.
C. An increase in heart rate is more likely with higher doses of dopamine and is not an optimal indicator of the drug's effectiveness for acute heart failure.
D. Client alertness is important but does not directly reflect the primary effects of dopamine on renal perfusion and cardiac output in acute heart failure.

A. Prothrombin time, fibrin level and eosinophil count B. Fibrin degradation products, lactic acid and complete blood count C. D-dimer, fibrinogen and fibrin degradation products D. Complete blood count, Complete metabolic panel and prothrombin time

Correct Answer is C

Explanation

A. This test set is incomplete for diagnosing DIC. While PT and fibrinogen are important, the eosinophil count is not a key test for DIC.
B. While fibrin degradation products are useful, lactic acid is not specific for DIC and may indicate other issues. A complete blood count is helpful but not definitive for diagnosing DIC.
C. These are key markers for DIC. An elevated D-dimer indicates clot formation and breakdown, while fibrinogen and fibrin degradation products are used to assess clotting and fibrinolysis, both of which are abnormal in DIC.
D. Complete blood count, complete metabolic panel, and prothrombin time are general tests and can give some clues, but they are not definitive for diagnosing DIC.
